Publication number: 20160035524Abstract: In some aspects, a relay control device includes a processor and a timer. The processor is electrically connectable to a relay that controls current flow to a load device. The processor causes the relay to be actuated at a first point in time so that a current flows to the load device. The processor determines an actuation duration for the relay from a measurement of the load current that is obtained with a current sense component. The processor determines a frequency of an input voltage or current from the measured load current. The processor synchronizes the timer with this frequency and identifies a zero-crossing point for a second load current based on the synchronized timer. The processor subsequently causes the relay to be actuated at a time that is offset from the zero-crossing point by the actuation duration.Type: ApplicationFiled: July 29, 2015Publication date: February 4, 2016Inventors: Dalibor Zulim, Richard L.

Patent number: 9064661Abstract: An example system for determining the actuation duration of a relay can include a relay, a current-sensing device, and a controller. The relay can have an actuation coil, and armature, and a first and second contact. The current-sensing device can measure a current through the actuation coil. The controller can actuate the relay. The controller can also receive from the current-sensing device a plurality of measurement values for the current through the actuation coil. The controller can determine an actuation duration based on a local minimum value for the plurality of measurement values. The actuation duration can correspond to a duration of a movement of an armature of the relay from the first contact of the relay to the second contact of the relay. An actuation delay of the relay can be calculated based on the zero-crossing time of an input voltage value and the actuation duration.Type: GrantFiled: June 26, 2012Date of Patent: June 23, 2015Assignee: ABL IP Holding LLCInventors: Richard L.

Patent number: 8296488Abstract: A method and system for addressing nodes in a multi-drop wired network are disclosed. In an embodiment nodes communicate via a two-way communication bus. Upon receipt of an address command, a first node assigns itself a first address, closes a switch to activate an output port of the first node to enable a second node to receive communications from the first node, and sends a second address onto the two-way communication bus. The second address is received by all previously addressed nodes, including a controller if used, as well as the second node, which is as yet unaddressed. Upon receipt of the second address, the second node repeats the process. If a node does not receive an acknowledgement that a subsequent node has addressed itself, that node deactivates its output port and terminates the network.Type: GrantFiled: April 27, 2010Date of Patent: October 23, 2012Assignee: ABL IP Holding LLCInventors: Richard L.

Patent number: 7950817Abstract: Display cases having lighting assemblies and methods of illuminating display cases with such lighting assemblies. Embodiments of the lighting assemblies may be used in display cases of any type and particularly in those where the purchaser selects via an external mechanism (e.g., buttons) a product from a variety of products stored inside the display, such as a vending machine. Lighting assemblies are installed within a vending machine, such as on or within the vending machine shelves or product dividers, and their light emission controlled depending on the product being selected from the vending machine. In on embodiment, all light sources within the vending machine except those illuminating the selected product are dimmed. In this way, the product being selected by the purchaser can be emphasized. In other embodiments, color or multi-color LEDs are used to emit light that best compliments the color of products housed within the vending machine.Type: GrantFiled: July 17, 2008Date of Patent: May 31, 2011Assignee: ABL IP Holding LLCInventors: Dalibor Zulim, Mark Anthony Hand, Forrest Starnes McCanless
